Iwatch6 can't send a small signal

If the transmission fails due to unstable signal, the operation method is as follows: 1. After the phone is unlocked, open the "watch" in the phone. 2. Then click "Watch" on the main page of the opened software. 3. Then click "WeChat" in the opened page to install the watch. 4. Then set it in the page that opens. Watches can receive SMS phone reminders from WeChat, but can't send SMS and WeChat. There may be several reasons: because the network signal in the place where the landlord is located is not good, iwatch has a fault when sending information. 2. Please turn off the network on iPhone first, then find a place with strong Wi-Fi signal to turn on the wireless network, and then turn on Bluetooth. 3. If you don't have Wi-Fi, you can use other people's hotspots.
